Shaft Seals

The New Seal ^® from New Way Air Bearings ^® is a brand new solution for industries requiring the use of axial and circumferential seals. Built on 25 years of experience with Externally Pressurized Porous Media (EPP), the New Seal ^® is a leak-free, wear-free seal for rotating equipment.

What Is the New Seal?

The New Seal utilizes rotating and non-rotating components in order to create a non-contact, rotating seal that still restricts gas and fluid flow at up to 30 PSI. The New Seal is composed of the following components:

1. Air Bearing inside of a flanged housing, which bolts to the casing of your machinery or driveshaft
2. A runner with an O-Ring mounted along its inner diameter that moves with the rotating shaft
3. A spacer, purposefully oversized to the runner which allows for clearance between the faces of the two air bearing surfaces
4. The outermost air bearing which acts as the seal housing

In effect it’s the internal O ring, spinning with the rotating shaft that provides the foundation for the seal. As the two halves of the air bearing are pressurized around the shaft, the 30 PSI of positive pressure repels fluid or particle intrusion into the bearing, maintaining non-contact sealing on both halves of the shaft

Markets and Applications

The New Seal is an ideal fit for any industry which demands a contaminant free operating environment for machinery whilst dealing with fine particulates, liquids, or product gases.

Liquid and Gas Sealing
For liquid or gas processes that requires face or circumferential seal, the New Seal provides an answer. Our EPP Media utilizes the permeable nature of carbon and graphite to prevent the backflow of fluids, gases, steam, or other mediums across the seal, bearing, or combination thereof. Applications include:

• Oil-free pumps
• Compressors
• Turbo expanders
• Fuel injection
• Bearing isolators
• Motors
• Generators

Dry and Bulk Powder Handling
In any environment where you’re moving bulk powders and fine particulates, the very material you’re working with is also your greatest enemy. Micron sized particles will work themselves into every nook and crevice of your machinery, inevitably choking off dynamic components and slowing down operations for maintenance or outright replacement. If your work environment is geographically isolated or deep underground, these delays can be costly, grinding your site to a halt as you replace a bearing that spalled due to particle infiltration. With the New Seals’ positive hydrostatic pressure barrier impervious to anything below 30 psi, you’ll never find yourself at a work stoppage due to a blown seal or gasket.

Applications include:

• Mixers
• Blenders
• Rotary air locks
• Vacuum systems
• Screw conveyors

Conventional Seal Replacement
New Way Air Bearings are renowned for their maintenance free operation and low cost of installation. With the ability to operate on process gases and requiring little retrofitting in order to be compatible with your existing infrastructure, The New Seal is a prime candidate for upgrading from:

• Hydrogen
• Labyrinth
• Packing
• Abradable
• Brush seals
